Functions

func BlockMultiSigProgram

func BlockMultiSigProgram(pubkeys []ed25519.PublicKey, nrequired int) ([]byte, error)

BlockMultiSigProgram returns a valid multisignature consensus program where nrequired of the keys in pubkeys are required to have signed the block for success. An ErrBadValue will be returned if nrequired is larger than the number of keys provided. The result is: BLOCKSIGHASH <pubkey>... <nrequired> <npubkeys> CHECKMULTISIG

func IsUnspendable

func IsUnspendable(prog []byte) bool

func P2SPMultiSigProgram

func P2SPMultiSigProgram(pubkeys []ed25519.PublicKey, nrequired int) ([]byte, error)

func ParseBlockMultiSigProgram

func ParseBlockMultiSigProgram(script []byte) ([]ed25519.PublicKey, int, error)

func ParseP2SPMultiSigProgram

func ParseP2SPMultiSigProgram(program []byte) ([]ed25519.PublicKey, int, error)
